2021 Mercedes-Benz GLC 300 AMG Line Prem + 4M A 2.0L Hybrid electric · MU67 LAB

This Mercedes-Benz GLC 300 AMG demonstrates a stable roadworthiness trend over the past two MOT cycles, with both tests—most recently on 29 January 2026—resulting in clean passes without defects or advisories. The absence of recurring issues across the 2025 and 2026 tests suggests that no critical components, such as suspension bushes, coil springs, or binding calipers, have been overlooked in routine maintenance. However, the gap between tests—just over seven months—is slightly longer than the DVSA’s recommended 12-month interval for this class of vehicle. While no faults were recorded, the extended period since the last test means some consumables, like brake pads and wiper blades, may now require attention. The recorded mileage of 40,417 miles, accumulated over approximately five years, aligns with typical usage patterns for a vehicle of this age. There are no visible gaps in mileage accumulation to suggest prolonged neglect, nor does the data indicate excessive wear from rapid mileage buildup. The most recent MOT, conducted at 39,000 miles, followed a steady progression from the previous test at 31,000 miles in February 2025. This pattern implies consistent, moderate usage rather than heavy or sporadic driving habits. Given the clean MOT history, a prospective buyer should prioritise a thorough inspection of high-wear items that fall outside the MOT’s scope, such as the condition of the suspension bushes, particularly at the rear, where AMG models often experience accelerated wear. The brake system—including disc thickness and caliper binding—should be scrutinised, as even minor issues can escalate quickly in performance-oriented vehicles. Additionally, the underbody should be checked for corrosion, especially around the sills and wheel arches, where salt ingress is common in older models. Finally, the exhaust system’s structural integrity should be verified, as catalytic converter damage or leaks are not always detectable during an MOT.
